Bridgehead

This repository contains all information and tools to deploy a bridgehead. If you have any questions about deploying a bridgehead, please contact us.

TODO: Insert comprehensive feature list of the bridgehead? Why would anyone install it?

TODO: TOC

Requirements

Before starting the installation process, please ensure that following software is available on your system:

Git

To check that you have a working git installation, please run

cd ~/;
git clone https://github.com/octocat/Hello-World.git;
cat ~/Hello-World/README;
rm -rf Hello-World;

If you see the output "Hello World!" your installation should be working.

Docker

To check your docker installation, you can try to execute dockers "Hello World" Image. The command is:

docker run --rm --name hello-world hello-world;

Docker will now download the "hello-world" docker image and try to execute it. After the download you should see a message starting with "Hello from Docker!".

NOTE: If the download of the image fails (e.g with "connection timed out" message), ensure that you have correctly set the proxy for the docker daemon. Refer to "Docker Daemon Proxy Configuration" in the "Pitfalls" section

You should also check, that the version of docker installed by you is newer than "1.20". To check this, just run

docker --version

Docker Compose

To check your docker-compose installation, please run the following command. It uses the "hello-world" image from the previous section:

docker-compose -f - up <<EOF
version: "3.9"
services:
  hello-world:
    image: hello-world
EOF

After executing the command, you should again see the message starting with "Hello from Docker!".

You should also ensure, that the version of docker-compose installed by you is newer than "2.XX". To check this, just run

docker-compose --version

systemd

You shouldn't need to install it yourself. If systemd is not available on your system you should get another system. To check if systemd is available on your system, please execute

systemctl --version

Getting Started

If your system passed all checks from ["Requirements" section], you are now ready to download the bridgehead.

First, clone the repository to the directory "/srv/docker/bridgehead":

sudo mkdir /srv/docker/;
sudo git clone https://github.com/samply/bridgehead.git /srv/docker/bridgehead;

adduser --no-create-home --disabled-login --ingroup docker --gecos "" bridgehead useradd -M -g docker -N -s /sbin/nologin bridgehead chown bridghead /srv/docker/bridgehead/ -R

Next, you need to configure a set of variables, specific for your site with not so high security concerns. You can visit the configuration template at GitHub. You can download the repositories contents and add them to the "bridgehead-config" directory.

sudo git submodule add -f https://github.com/samply/bridgehead-config.git ./site-config;

NOTE: If you are part of the CCP-IT we will provide you another link for the configuration.

You should now be able to run a bridgehead instance. To check if everything works, execute the following:

sudo ./lib/init-test-environment.sh;
sudo ./start-bridgehead.sh <dktk/gbn/c4>;

You should now be able to access the landing page on your system, e.g "http:///"

To remove the test-environment, run (make sure you don't have other docker services installed on this system, docker volume prune is destructive!)

sudo ./stop-bridgehead.sh <dktk/gbn/c4>;
sudo docker volume prune;

For a server, we highly recommend that you install the system units for managing the bridgehead, provided by us. . You can do this by executing the setup-bridgehead-units.sh script:

sudo ./lib/setup-bridgehead-units.sh

Finally, you need to configure your sites secrets. These are places as configuration for each bridgeheads system unit. Refer to the section for your specific project:

For Any Project you need to set the proxy in Update too

[Service]
Environment=http_proxy=
Environment=https_proxy=

DKTK/C4

You can create the site specific configuration with:

sudo systemctl edit bridgehead@dktk.service;

This will open your default editor allowing you to edit the docker system units configuration. Insert the following lines in the editor and define your machines secrets. You share some of the ID-Management secrets with the central patientlist (Mainz) and controlnumbergenerator (Frankfurt). Refer to the "Configuration" section for this.

[Service]
Environment=HOSTIP=
Environment=HOST=
Environment=HTTP_PROXY_USER=
Environment=HTTP_PROXY_PASSWORD=
Environment=HTTPS_PROXY_USER=
Environment=HTTPS_PROXY_PASSWORD=
Environment=CONNECTOR_POSTGRES_PASS=
Environment=ML_DB_PASS=
Environment=MAGICPL_API_KEY=
Environment=MAGICPL_MAINZELLISTE_API_KEY=
Environment=MAGICPL_API_KEY_CONNECTOR=
Environment=MAGICPL_MAINZELLISTE_CENTRAL_API_KEY=
Environment=MAGICPL_CENTRAL_API_KEY=
Environment=MAGICPL_OIDC_CLIENT_ID=
Environment=MAGICPL_OIDC_CLIENT_SECRET=

To make the configuration effective, you need to tell systemd to reload the configuration and restart the docker service:

sudo systemctl daemon-reload;
sudo systemctl bridgehead@dktk.service;

C4

You can create the site specific configuration with:

sudo systemctl edit bridgehead@c4.service;

This will open your default editor allowing you to edit the docker system units configuration. Insert the following lines in the editor and define your machines secrets. You share some of the ID-Management secrets with the central patientlist (Mainz) and controlnumbergenerator (Frankfurt). Refer to the "Configuration" section for this.

[Service]
Environment=HOSTIP=
Environment=HOST=
Environment=HTTP_PROXY_USER=
Environment=HTTP_PROXY_PASSWORD=
Environment=HTTPS_PROXY_USER=
Environment=HTTPS_PROXY_PASSWORD=
Environment=CONNECTOR_POSTGRES_PASS=
Environment=STORE_POSTGRES_PASS=
Environment=ML_DB_PASS=
Environment=MAGICPL_API_KEY=
Environment=MAGICPL_MAINZELLISTE_API_KEY=
Environment=MAGICPL_API_KEY_CONNECTOR=
Environment=MAGICPL_MAINZELLISTE_CENTRAL_API_KEY=
Environment=MAGICPL_CENTRAL_API_KEY=
Environment=MAGICPL_OIDC_CLIENT_ID=
Environment=MAGICPL_OIDC_CLIENT_SECRET=

To make the configuration effective, you need to tell systemd to reload the configuration and restart the docker service:

sudo systemctl daemon-reload;
sudo systemctl bridgehead@c4.service;

GBA/BBMRI-ERIC

You can create the site specific configuration with:

sudo systemctl edit bridgehead@gbn.service;

This will open your default editor allowing you to edit the docker system units configuration. Insert the following lines in the editor and define your machines secrets.

[Service]
Environment=HOSTIP=
Environment=HOST=
Environment=HTTP_PROXY_USER=
Environment=HTTP_PROXY_PASSWORD=
Environment=HTTPS_PROXY_USER=
Environment=HTTPS_PROXY_PASSWORD=
Environment=CONNECTOR_POSTGRES_PASS=

To make the configuration effective, you need to tell systemd to reload the configuration and restart the docker service:

sudo systemctl daemon-reload;
sudo systemctl bridgehead@gbn.service;

Developers

Because some developers machines doesn't support system units (e.g Windows Subsystem for Linux), we provide a dev environment configuration script. It is not recommended to use this script in production!

Managing your Bridgehead

TODO: Rewrite this section (restart, stop, uninstall, manual updates)

On a Server

Start

This will start a not running bridgehead system unit:

sudo systemctl start bridgehead@<dktk/c4/gbn>

Stop

This will stop a running bridgehead system unit:

sudo systemctl stop bridgehead@<dktk/c4/gbn>

Update

This will update bridgehead system unit:

sudo systemctl start bridgehead-update@<dktk/c4/gbn>

Remove the Bridgehead System Units

If, for some reason you want to remove the installed bridgehead units, we added a script you can execute:

sudo ./lib/remove-bridgehead-units.sh

On Developers Machine

For developers, we provide additional scripts for starting and stopping the specif bridgehead:

Start

This shell script start a specified bridgehead. Choose between "dktk", "c4" and "gbn".

./start-bridgehead <dktk/c4/gbn>

Stop

This shell script stops a specified bridgehead. Choose between "dktk", "c4" and "gbn".

./stop-bridgehead <dktk/c4/gbn>

Update

This shell script updates the configuration for all bridgeheads installed on your system.

./update-bridgehead

NOTE: If you want to regularly update your developing instance, you can create a CRON job that executes this script.

Pitfalls

Git Proxy Configuration

Unlike most other tools, git doesn't use the default proxy variables "http_proxy" and "https_proxy". To make git use a proxy, you will need to adjust the global git configuration:

sudo git config --global http.proxy http://<your-proxy-host>:<your-proxy-port>;
sudo git config --global https.proxy http://<your-proxy-host>:<your-proxy-port>;

NOTE: Some proxies may require user and password authentication. You can adjust the settings like this: "http://:@:". NOTE: It is also possible that a proxy requires https protocol, so you can replace this to.

You can check that the updated configuration with

sudo git config --global --list;

Docker Daemon Proxy Configuration

Docker has a background daemon, responsible for downloading images and starting them. To configure the proxy for this daemon, use the systemctl command:

sudo systemctl edit docker

This will open your default editor allowing you to edit the docker system units configuration. Insert the following lines in the editor, replace and with the corresponding values for your machine and save the file:

[Service]
Environment=HTTP_PROXY=http://<your-proxy-host>:<your-proxy-port>
Environment=HTTPS_PROXY=http://<your-proxy-host>:<your-proxy-port>
Environment=FTP_PROXY=http://<your-proxy-host>:<your-proxy-port>

NOTE: Some proxies may require user and password authentication. You can adjust the settings like this: "http://:@:". NOTE: It is also possible that a proxy requires https protocol, so you can replace this to.

The file should now be at the location "/etc/systemd/system/docker.service.d/override.conf". You can proof check with

cat /etc/systemd/system/docker.service.d/override.conf;

To make the configuration effective, you need to tell systemd to reload the configuration and restart the docker service:

sudo systemctl daemon-reload;
sudo systemctl restart docker;
